So which program is showing the changes the way you want them? Your description of the problem isn't very clear.
picasa photo viewer is showing those changed pictures
If you are making your changes using Picasa then the changes are being made to the JPEG preview, not the raw data. Smart previews are only used by Lightroom. However, those smart previews are only used by Lightroom. They are previews of the raw image data. You cannot make changes using Picasa, and expect them to show in Lightroom.
